Somewhat related, but Wikipedia actually has a "special page" for searching external links, which I've had a lot of fun with: https://en.wikipedia.org/wiki/Special:LinkSearch https://en.wikipedia.org/wiki/Special:LinkSearch You can e.g. search for all external links to HN, to pg's website, or to any Twitter user's tweets: https://en.wikipedia.org/wiki/Special:LinkSearch?target=news.ycombinator.com https://en.wikipedia.org/wiki/Special:LinkSearch?target=news... https://en.wikipedia.org/wiki/Special:LinkSearch?target=paulgraham.com https://en.wikipedia.org/wiki/Special:LinkSearch?target=paul... https://en.wikipedia.org/wiki/Special:LinkSearch?target=twitter.com%2Felonmusk https://en.wikipedia.org/wiki/Special:LinkSearch?target=twit... You can also use it to get a sense of the adoption rates of new gTLDs: https://en.wikipedia.org/wiki/Special:LinkSearch?target=*.ngo https://en.wikipedia.org/wiki/Special:LinkSearch?target=*.ng... https://en.wikipedia.org/wiki/Special:LinkSearch?target=*.design https://en.wikipedia.org/wiki/Special:LinkSearch?target=*.de... https://en.wikipedia.org/wiki/Special:LinkSearch?target=*.press https://en.wikipedia.org/wiki/Special:LinkSearch?target=*.pr... https://en.wikipedia.org/wiki/Special:LinkSearch?target=*.club https://en.wikipedia.org/wiki/Special:LinkSearch?target=*.cl... (I only wish there's a way to optionally filter out links originating from Talk pages, since those sometimes introduce a lot of noise, depending on your purpose) All the other "special pages" are listed at: https://en.wikipedia.org/wiki/Help:Special_page https://en.wikipedia.org/wiki/Help:Special_page
